What does incoming mail server mean

Difference between SMTP, IMAP and POP3

All three are Logswith which e-mails are made possible.
In short: Per SMTP (Simple Mail Transfer Protocol) send you emails - by IMAP (Internet Message Access Protocol) and POP3 (Post Office Protocol Version 3) calling you her from the server.


But what is the difference between IMAP and POP3 and why is IMAP usually the better choice?


IMAP synchronized your emails between Server and the e-mail programs on your computer, tablet or smartphone.
So you can read, edit or delete your emails anywhere. Regardless of which device and who is using it: you are always on the same status like the other devices.
You can see the reference, i.e. what is “on the server” in your mailbox and can be synchronized, in the webmailer.


With POP3 you just download emails down. Your emails load as Copy from the server to your computer, tablet or smartphone. There you can read, answer or delete them - but only locally.
POP3 comes from the time when server storage space was scarce and so e-mails are classically after a certain period of time deleted on the server.

The disadvantages of POP3: Your other devices and also the server experience nothing of these changes and our server backups only include the current status of the emails that have not yet been deleted. Even sent emails are not on the server, but only in your client.
